An approach is described for use in the varietal characterization of hop (Humulus lupulus L.) varieties. The study focuses on commercial hop varieties and was timed to coincide with the 2008 commercial hop harvest in Tasmania, Australia. Analysis of hop extracts was performed using GC-MS. A 60 m capillary column was employed to increase efficiency to permit the use of a quadrupole mass spectrometer in place of a time of flight mass spectrometer that is more commonly used for this type of analysis. A set of characterization functions were derived from discriminant analysis which were highly suitable for varietal characterization of the eight commercial varieties included in the study, namely Willamette, Victoria, Pride of Ringwood, Cascade, Southern Hallertau, Millennium, Southern Saaz, and Super Pride.
描述了一种用于啤酒花(Humulus lupulus L.)品种特征描述的方法。本研究集中于商业啤酒花品种,时间与 2008 年澳大利亚塔斯马尼亚州的商业啤酒花收获期相吻合。使用 GC-MS 对啤酒花提取物进行分析。采用 60m 毛细管柱以提高效率,从而可以使用四极杆质谱仪代替更常用于此类分析的飞行时间质谱仪。从判别分析中得出了一组特征函数,非常适合用于对研究中包括的八个商业品种(威拉米特、维多利亚、林伍德之傲、卡斯卡特、南哈勒陶、千禧、南萨兹和超级林伍德之傲)进行品种特征描述。
